Neural Scale FaaS

(Currently only supports Java)

POST a JSON body structured as follows'route: "{route}", "functionBody": "request -> { ; return response; }; "; to the https://:/addFunction and your function will be served.

Your function will be executed in a sandbox that will have several libraries and helper functionsavailable to you.

The functions leverage the Netty framework and you will have access to the full http stack in netty. https://netty.io We have provided Moshi for working with JSON https://github.com/square/moshi We have provided the full Amazon SDK for working with AWS We have provided Jedis for working with redis We have provided a kafka client and a cassandra client

Your function needs to have the signature Function<HttpRequest, HttpResponse> in order to correctly work.

An Example

this loads a function

 $> curl -k https://localhost:8080/addFunction \
    -X POST -d '{"route": "/hello", 
    "functionBody": "request -> { 
      String respMsg = \"OK\"; 
    
      FullHttpResponse response = new DefaultFullHttpResponse(
      HttpVersion.HTTP_1_1, 
      HttpResponseStatus.OK, 
      Unpooled.copiedBuffer(respMsg.getBytes())); 
    
      response.headers().set(CONTENT_TYPE, \"text\/plain\"); 
      response.headers().setInt(CONTENT_LENGTH, respMsg.length());  
    
      return response; } " 
    
    } ' -vvv
 $> OK

and to call the function:

$> cur l -k https://localhost:8080/hello
$> ok

Triggering Events

• Http req
• Hashed Wheel Timer
• Cloudtrail < Give examples of each >

To Start the server

./bin/serverStart.sh <log_level>

Docker

A Docker container is available for both local development and running at scale

Scale out

• DHT hashed on route leveraging Trailhead
• < N > servers that access routes and functions via a K,V store. Route is K | class ByteCode is V.
